ʻO ka lepa i ulana ʻiapili i ka lepa i pili i ka paipu ma ke kaula. Ke hoʻolālā ʻia, hiki ke mālama ʻia e ka flange wehe. ʻO ka pōmaikaʻi, ʻaʻole pono ke kuʻi ʻana a ʻoi aku ka liʻiliʻi o ka torque hou i ka cylinder a i ʻole ka paipu i ka wā i deformed ka flange. ʻO ka hemahema ʻo ia ka nui o ka mānoanoa flange a ʻoi aku ke kumukūʻai. He kūpono ia no ka pili paipu kiʻekiʻe.
ʻO ka flange wili ke ʻano o ka flange non-weld, e hana ana i ka lua o loko o ka flange i loko o ka pae paipu a hoʻopili me ka paipu me ka milo. Hoʻohālikelike ʻia me ka flange welded flat a i ʻole butt welded flange, threaded flange i nā hiʻohiʻona o ka hoʻonohonoho maʻalahi a me ka mālama ʻana, a hiki ke hoʻohana ʻia i kekahi mau pipeline i ʻae ʻole ʻia e welded ma ka pūnaewele. Loaʻa ka ikaika o nā flanges Alloy, akā ʻaʻole maʻalahi i ka weld, a i ʻole ka maikaʻi ʻole o ka hana kuʻi ʻana, hiki ke koho i nā flanges threaded. Eia nō naʻe, ʻōlelo ʻia ʻaʻole e hoʻohana i nā flanges threaded e pale aku i ka leakage ke kiʻekiʻe ka mahana o ka paipu ma mua o 260 degere centigrade a ma lalo o -45 degere centigrade.
